To all whom t may concern:

Be it known `that ne (l) Jarras iV. Fnaznnz, (2) filmen E. Hansen',citizens of the United lStates, residing at Cleveland, in the county oi'Cuyahoga and State ot Ohio, have invented a certain new and usefulimprove nient in Hose Connections, ot which the following; is a full,cle*L and exact description, reference being had lo the accompanyingdrawings.

rl-hisinvention relates generally to hose connection for inl-latinoltires and more par.- ticnlarly to certain 'inmrovenients upon the hoseconnection slionimr'l described in our applica-tion Serial No. 66,415,liled Deceniher i3, 1915. and in this application We disclaim anythingcovered in the aforesaid application.

The ohiect or' our present invention is to provide a double ended hoseconnection whereby a more convenient connection is provided, as it veryfrequently happens that considerable difficulty is encountered in turning a single ended connection to bring it into engagement with the tirevalve stem.

Another object of our invention is to provide a double ended hoseconnection, in which the valve at one end will act as a stop or thevalve at the opposite end.

With these and various other objects in view our invention consists inthe novel .teatures of construction hereinafter fully de scribed andpointed ont in the claim.

ln the drawings forming part oi this speci- 'lication Figure 1 isadetail perspective view of our improved hose connection; Fig. 2 is aside view of the same; an Fig. 3 is a ver tical sectional View partly inelevation.

in the practical embodiment of our invention We employ a casingI Apreferably eylind drical in shape and -lia'vlng a centrally arrangedlateral projection B constructed with a central air inlet C, a stein Dhaving a kcentrai here being;n connected to the extension B by.threading or otherwise, or if preferred this stem and extension can emade integral. The casing rovided with oppositeiy disposed annularvvalve seats E upon which seat the disk members F of the valves, saiddisk members being preferably ot rubber or other flexible material, butit will ne understood that the said disks can loe made oi' any othersuitable material if desired.

The disks F are secured in place upon the seats E by means of nuts G,the outer ends of ,said nuts being preierahly hexagonal in shape asshown. Vtorking Within each nut and also in the adjacent disk is themovable member H of the valve, each movable member being bored as shownat l and apertured as shown at l. and having the cap portion L,substantially the saine as shev and de* scribed in the applicationpreviously reierred to.

lli/hen the tire valve stem lVi is inserted in either end or the casingit contacts with the movable4 member or the valve and forces the sameinwardly. This movement tends to slightly llex the disk F and theaperture K is uncovered so that air can pass freely into the stem Mthrough the central passage or bore ll and it will he noted that whenone valve is 'forced inwardly vthe cap portion thereof will contact withthe cap portion of the other valve which will :1ct as a stop and preventany further inward movement, and this pressure upon the second cap tendsto hold the unused valve more firmly upon its seat.

it is only necessary to move the central portion or the valve a veryshort distance and consequently all of the parts are so constructed thatthese inner ends Will be comparatively close together while both valvesare in their normal closed positions; By making" the connection doubleended, and providing two opposed valves, a muchlnore convenient deviceis provided than one having a single operating en as with a sti hose towhich the connection is attached it frequently happens that greatdiliiculty is experienced in positioning: the connection for receivingthe tire valve stein,- and this diiieulty will be .completely avoided bythe present construction. Y

Furthermore the life of the device is practically doubled for the reasonthat two valves are employed instead of one. While we have shown oneform. of device for carrying ont .our invention it is obvious thatcertain changes and modilications can he made thereto Without departingfrom the broad principle of the invention Within the scope of theappended claim.
